I wrote this Oil Analysis report about my Mercedes 500SL:
500SL
I had a Blackstone Kit and a Wix Kit and figured I may as well try them both. I took the Oil Sample and mixed it throughly back and forth between two sample bottles and sent one to each lab. I got the Blackstone report back quickly and used it to make the report. I got the Wix one back today. They are similar except they are significantly different on Aluminum.
It's like have two watches. If you only have one - you know what time it is. If you have two that are 10 minutes apart - you have no idea.
